Answer 1:
Yes, hog circulatory systems are pretty
much like ours. Veins take blood from everywhere
back to the heart, the arteries take blood out
from the heart, and the capillaries between the
arteries and veins is where blood exchanges
resources and wastes with the cells.
Hogs are mammals like us, so most of our
systems are pretty similar. Lots of blood
vessels even have the same names in humans and
other animals. If you learn the circulatory system
on a hog, you will have a very good understanding
of the human circulatory system.
How many jobs can you think of that the
circulatory system does for us?
